Medically speaking, slow metabolism is one of the main causes for cold intolerance. Some people (often slim men/ women) do not tolerate cold environments simply because they have minimal body fat and are unable to keep warm. General poor health, faulty diet and medical conditions such as anorexia nervosa, hypothyroidism, and other chronic illness can also lead to intolerance.
